Does the error happen at close the to the same number of files (or bytes of data) everytime? If so, you may want to try backing up your data in 4 or 5 parts, and let the system rest for a bit in between. Example, I think I remember you saying that it fails around 5000 files, try making several backups of around 3000-4000 files each with a 3-5 min cooldown in between. I experienced similar problems when copying more than around 64MB from CDROM->IDE drive, and it worked if I copied in small chunks and gave it a chance to rest in between. Why letting a computer rest helps anything is beyond me, but all I know is it worked for me :) -Ben ------ Forwarded Message: ------ To: openbeos@xxxxxxxxxxxxx From: "Kevin Field" <kev@xxxxxxxxxxxxx> Subject: [openbeos] Re: need help, file copying problems! Date: Sat, 24 Jul 2004 21:38:28 -0400 EDT Shoot. I really don't want to reformat it, 'cause I've screwed my backup drive when I originally thought that it was the problem. :| I guess I'll try copying bits and pieces of the most important stuff just in case, and then start afresh and see what else I can recover... Thanks for all your help, Kev
